IA. Analysis of Solar Active Regions and Activity from 04-2100Z to 05-2100Z

Solar activity has been at high levels for the past 24 hours. The largest solar event of the period was a M7 event observed at 05/0947Z from Region 2205 (N16E56). There are currently 8 numbered sunspot regions on the disk.
IB. Solar Activity Forecast
Solar activity is likely to be moderate with a chance for X-class flares on days one, two, and three (06 Nov, 07 Nov, 08 Nov).
IIA. Geophysical Activity Summary 04-2100Z to 05-2100Z
The geomagnetic field has been at quiet to active levels for the past 24 hours. Solar wind speed, as measured by the ACE spacecraft, reached a peak speed of 597 km/s at 05/1939Z. Total IMF reached 12 nT at 05/0521Z. The maximum southward component of Bz reached -7 nT at 05/0647Z.
IIB. Geophysical Activity Forecast
The geomagnetic field is expected to be at quiet to unsettled levels on days one and three (06 Nov, 08 Nov) and quiet to active levels on day two (07 Nov). Protons have a slight chance of crossing threshold on days one, two, and three (06 Nov, 07 Nov, 08 Nov).
